Mishimoto Transmission Thermal Bypass Valve Kit

Your 2012-2018 Jeep Wrangler JK's transmission is the heart of its drivetrain, and maintaining its peak performance is crucial. The Mishimoto Transmission Thermal Bypass Valve Kit is designed to ensure your transmission stays cool, no matter the conditions. This kit replaces the stock thermostatic bypass valve, which can fail, leading to potential overheating issues. With Mishimoto's solution, you can enjoy peace of mind knowing your transmission is protected.

Key Features and Benefits

The Mishimoto Performance Thermostatic Bypass Valve offers several advantages over the original equipment. It features a fully-serviceable and removable thermostat, allowing you to customize your setup to suit your needs. In hot climates, the thermostat can be replaced with the included bypass to ensure full flow to the transmission cooler at all times. This innovative design also provides increased flow over the stock valve, ensuring your transmission cooler operates at peak efficiency. The included thermostat opens at the stock temperature of 160°F (71°C), but can be customized further with any available Mishimoto thermostat.
  • Increased Flow: Enhanced flow for improved cooling efficiency.
  • Customizable Thermostat: Adjust the valve to suit your specific environment and driving habits.

Why Choose Mishimoto?

Mishimoto is known for its high-quality, durable products, and the Transmission Thermal Bypass Valve Kit is no exception. Made from aircraft-grade aluminum and anodized for added strength, this valve is built to withstand the harshest environments. The direct-fit design ensures a simple installation process, and the Mishimoto Lifetime Warranty provides peace of mind. Whether you're a daily driver or an off-road enthusiast, the Mishimoto Transmission Thermal Bypass Valve Kit is the perfect solution to keep your Jeep Wrangler JK's transmission running smoothly and efficiently.
